Video: Chris Brown Performing National Anthem at Boxing Match

Before World Championship Boxing Match was kicked off on May 1, Chris Brown took the center stage and performed "The Star-Spangled Banner". The R&B performer showcased his rendition of the National Anthem prior to Floyd Mayweather, Jr.'s fight against Shane Mosley.

The Saturday match was held at the MGM Grand Garden Arena in Las Vegas and was broadcast by HBO. It ended with Floyd winning over Shane. "It's a contact sport, and you're going to get hit. But when you get hit, you suck it up and keep on fighting," Floyd said upon his victory. "That's what I did. I'm happy we finally had a chance to fight. This is a fight the fans have been looking forward to for a long time, and they deserve it."
